T0 all whom, it may concern:

Be it known that I, FREDERICK L. Pr-AHL, a. citizen of the UnitedStates, residing at Akron, in the county of Summit and State of Ohio,have invented certain new and useful Improvements in Gasolene-Gage Strutures; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. Y

This invention relates to improvements 1n indicators for liquidcontaining tanks or vessels.

The main object of the invention is to provide a mounting for anindicator ofthis.

character in which the indicating dial is exposed and the mountingarranged on the outer face of the tank to which the indicator isapplied.

Anc-ther object of the invention is to p rovide simple and efficientmeans for centering and supporting the indicator.

lVith these and other objects in view, the invention consists of certainnovel features of construction,- and the combination and ar,- rangementof parts as will be more fully described and claimed.

vIn the accompanying drawings: Figure 1 represents a perspective view ofa portion of a tank with this improved indlcator applied, parts beingbroken outg'Fig. 2 is a plan View with the outer clamping bandremoved:Fig. 3 is a transverse vertical section thereof taken on the line 3-3 ofFig. 1; Fig. 4 is a perspective view of the annular supporting member ofthe mounting detached.

1n the embodiment illustrated 1 denotes the indicator to which thisimprovement is applied and Q denotes the tank within which the indicatoris mounted. The tank 2 as shown is c vlindrically formed but it isobvious that the gage may be applied to any style o'f tank. This tank 2has an opening 3 in its upper face to receive the mounting whichsupports the indicator, said opening being shouldered to form asupporting flange 4 on'which the flange ofthe dial cup or indicatorsupport is designed to be seated as will be hereinafter described, theouter face of the flange of said support being thus arranged flush withthe outenface of the tank.

The indicator 1 as shown comprises a iioat Lguiding tube 5 which issecured to the under side G of a dial supporting cup said cup 4 havingonits outer edgean annular radially' Vprojecting Bange 8. The floatguiding tube 5 has a longitudinally extending slot 9 through whichprojects a radial finger 10 on the tioat 11 arranged within the tube 5,said finger being slidably engaged with said slot whereby the float isheld against rotationbut 1s permitted to freely rise and fall Within thetube with the rising and falling of the liquid inthe tank 2. 1

A skeleton' bearing plate 12 is secured toly the lower end of the tube 5and an up-.l

wardly projecting float operated shaft 13 is?. 70

revolubly mounted in said plate 12 and the upper end thereof projectsthrough the bottom 6 of cup 7 and the dial 14 mounted in said cup. Unthe upper end of the shaft 13 is fxedly mourned an 'indicating fingerorl pointer 15 which is adapted to co-act with the scale on the dialplate. The shaft 13 is preferably rectangular in cross section and istwisted so that the sides and corners thereof are in spiral form. Thefloat 11 has a centrall)7 disposed rectangular assage which is s idablyengaged with the slia-ft 13 so that the rising and lowering of the floatwill revolve the shaft 13 by reason of its spiral formation and thesliding engagement of the tioat therewith. When the shaft 13 is thusoperated the pointer 15 will be revolved in Aone direction or the otherand will cci-act' with the scale on the dial plate to indicate. thequantity of liquid in the tank.

transparent plate 16 covers the-fdi'al 14 and the periphery thereofextends tlushgwith the periphery of the radial iiange,- said plateresting on said flange preferably having a. gasket 17 arrangedbetweenthe plate and said flange. f

The indicator mounting or support comprises an annular plate 20 providedon its upper face with Ia plurality of spaced centering lugs 21arranged` adjacenttheperiphery of saidplate and spaced from the inneredge thereof a distance equal to the width of the flange 8 .on the dialcup 6, said flange 8 being adapted to rest on said plate Q0 and be heldagainstlateral movement by the centering lugs 21. These lugs Q1 areprovided with screw threaded sockets 29 opening through the upper endsthereof which are' designed to receive the fastening screws which securean annular clamping plate Q3 in position for holding the cover 16reliably between said'plate 23 and the plate 20, a gasket 24 beingpreferably ssl' arranged between the plate Q3 and the glass disk orplate i6.

The plate 20 is provided at its periphery with an upstanding collarQiroin the edge ot which extends an annular radial flange 2G which isdesigned to rest on the annular shoulder formed around the opening 8 inthe tank 2, said flange QG being of a width corresponding to. the widthof the shoulder and the circumference ot the collar 25 corresponding tothe circumference ot the inner edge ot said shoulder whereby said collar25 is fitted closely Within the tank opening. .After the indicator l hasbeen inserted in the supporting plate :9.0 and secured thereto by theclamping plate Q3, the piate 20 vwith. the. indicator attached ismounted on the tank 2, the indicator being iirst inserted through theopening .in said ltank and the flange 26 of said plate.v is se-v cured.'to the shoulder around 'the opening .3f-by means of fastening screws orother suitable elements. When the parts are thus assembled it will beobvious that the outer faces of the' tia-nge 26 and the plate 23 will beiiush with each other and with the outer tace of the tank 2 and that theindicator be reliably supported within the tank and held by thecentering lugs 2l against lateral movement.

l `While I have described my invention with more or less minuteness asregards details and as being embodied in certain vprecise forms, do `notdesire to be limited thereto unduly any more than is pointed out in theclaims. @n the contrary, it contemplate all lproper changes in ori'n,construction and arrangement the omission of immaterial elements andsubstitutionof equivalents as circumstances may suggest, or renderekpedient.

Y I claim as my invention:

l. An indicator 'support comprising an annular plate having an inneredge, center- Loeaeea said lugs, a clampingvplate fitted within saidupstanding collar and resting on said 5 lugs, means for securing saidclamping plate to said lugs, and a flange extending laterally from theupper edge of the said unstanding collar with its upper face flush `withthe upper tace of the clamping plate.

3. The combination with a liquid containn ing tank having an aperturetherein for the reception ot a gage, a collar fitted in said opening andhaving an annular plate eX- tendi'ng inwardly therefrom, 'a dialsupporting cup seated on said plate, a tube secured to and dependingfrom said cup, a iioatslidably located in said tube, means forpreventing rotation of said float, a plate at the lower end ot saidtube, a shaft jour- 7 naled in the supporting cup and in the plate att-he lower end of said tube, said shaft passing through the iot andcoperatingtherewith, whereby the s iatt is rotated during the verticaltravel/oiV the float, a pointer carried by the upper projecting end ofthe shaft, a transparent cover for said supporting cup, and means forholding said transparent cover and supporting cup on said ledge.

ln testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FREDERICK L. rrAHL.
